[英]Using SimpleCursorAdapter.ViewBinder to change color in a listView. android
I was trying to change color on a text in a ListView, so I created ViewBinder but my text is still white, nothing change, what can I do with it? 我试图在ListView中更改文本的颜色,所以我创建了ViewBinder,但我的文本仍然是白色,没有任何变化,该怎么办?
// map each name to a TextView
String[] from = new String[] { "event" };
int[] to = new int[] { R.id.countryTextView };
conAdapter = new SimpleCursorAdapter(Clock.this, R.layout.day_plan, null, from, to);
setListAdapter(conAdapter); // set adapter
SimpleCursorAdapter.ViewBinder binder = new SimpleCursorAdapter.ViewBinder() {
@Override
public boolean setViewValue(View view, Cursor cursor, int columnIndex){
int getIndex = cursor.getColumnIndex("colour");
String color = cursor.getString(getIndex);
tv = (TextView)findViewById(R.id.countryTextView);
tv.setTextColor(Color.BLUE);
if(color.equals("Green"))
{
tv.setTextColor(Color.rgb(0,255,0));
return true;
}
return false;
}};
Did you call conAdapter.setViewBinder(SimpleCursorAdapter.ViewBinder)
? 您是否致电
conAdapter.setViewBinder(SimpleCursorAdapter.ViewBinder)
? That is, are you sure those methods are actually being called? 也就是说,您确定实际上正在调用这些方法吗?
Also change one of those lines: 还要更改以下几行之一:
tv = (TextView)view.findViewById(R.id.countryTextView); // <-- add 'view.'
